A small town currently has a population of 15,000. Each year the population decreases by 2.25%. What will the population be in 8 years
Answer: 12,503 people
Step-by-step explanation:
This is an exponential decrease so to find the population in 8 years you have to use a future value formula:
= Amount * (1 + rate) ^ number of years
= 15,000 ( 1 + (-2.25%)) ⁸
= 15,000 * (1 - 2.25%)⁸
= 12,503.32
= 12,503 people

CAN SOMEONE HELP ME WITH THIS PLEASE???
Answer:
Its 2x + 0.
Step-by-step explanation:
This is because, the 2 represents the slope or rate of change and the 0 represents the initial value/y-intercept, since the snow started at 0 inches.

Answer:
3734.95
Step-by-step explanation:
Pi = 3.14 to find the radius of a circle we multiply the circumference and Pi. Then square it. So, 34.48x3.14 = 108.2672 then 108.2672² = 3734.94651 which rounds to 3734.95

Answer:
1/2
Step-by-step explanation:
As you probably know 10 is double the size/amount of 5, but instead of just putting 2 you would put 1/2. That is because it is a scale factor of a scale drawing, which is not the same size and is supposed to be smaller because you can't draw a house on a paper that would fit it literally ;)

Logan is taking a loan out to buy a $4000 right for his wife. He has two finance options listed below. Which should he choose? Option a- a five year loan with a %7 interest rate compounded quarterly l. Option b- an eight year loan with a 5.5% interest rate compounded annually
Answer:
The most convenient option for Logan is A, since he will pay a lower amount than if he chose option B.
Step-by-step explanation:
Given that Logan is taking a loan out to buy a $ 4000 right for his wife, and he has two finance options, Option A, which gives a five year loan with a% 7 interest rate compounded quarterly, and Option B, which gives an eight year loan with a 5.5% interest rate compounded annually, to determine which option should be chosen, the following calculation must be performed:
Option A:
X = 4,000 (1 + 0.07 / 3) ^ 5x3
X = 5,653.49
Option B:
X = 4,000 (1 + 5.5 / 1) ^ 8x1
X = 6,138.75
Thus, the most convenient option for Logan is A, since he will pay a lower amount than if he chose option B.
write an equation of the line that passes through (0 0) and (2 6)
Answer:
y = 3x
Step-by-step explanation:
Slope equation:
y2 - y1
--------
x2 - x1
----------------------------------------------------------------------------------------------------------------
6 - 0 6
m = ----------- = ----- = 3
2 - 0 2
Your slope is 3.
----------------------------------------------------------------------------------------------------------------
Equation:
y = mx + b
Plug in the slope and you get:
y = 3x + b
----------------------------------------------------------------------------------------------------------------
Now to find b, you can use either coordinate point. So I will show you both ways :)
(0,0) (2,6)
0 = 3(0) + b 6 = 3(2) + b
Multiply 0 and 3 Multiply 2 and 3
0 = 0 + b 6 = 6 + b
Subtract 0 to 0 Subtract 6 from 6
0 = b 0 = b
There is no y-intercept
----------------------------------------------------------------------------------------------------------------
Your answer: y = 3x
Hope this helped :)

In the U.S., from 2004-2015, the correlation coefficient for the relationship between the size of a cell phone data plan, x, and the number of text messages sent, y, is r =0.97. Describe what this means about the relationship between the data plan size and the number of text messages sent in the U.S.
Answer options:
- There is no correlation between the size of the data plan and the number of text messages in the US.
- There is a weak positive linear correlation between the size of a cell phone data plan and the number of text messages sent.
- There is a strong negative linear correlation between the size of a cell phone data plan and the number of text messages sent.
- There is a strong positive linear correlation between the size of a cell phone data plan and the number of text messages sent.
I'd appreciate if you included an explanation, but an answer is fine.
Answer:
D. There is a strong positive linear correlation between the size of a cell phone data plan and the number of text messages sent.Step-by-step explanation:
We have r = 0.97
Correlation coefficients whose magnitude are between 0.9 and 1.0 indicate variables which can be considered very highly correlated (as per below table)r = (0.9, 1.0) very highly correlated. r = (0.7, 0.9) highly correlated. r = (0.5, 0.7) moderately correlated. r = (0.3, 0.5) low correlation. r = (0, 0.3) little to no correlation.Same applies to negative side
Correct choice is
D. There is a strong positive linear correlation between the size of a cell phone data plan and the number of text messages sent.To explain it in very simple way, consider a linear equation:
y = mx + bNumber of text messages is the linear function of the data plan. r = 0.97 shows this relationship is almost a perfect line with positive slope.
- There is a strong positive linear correlation between the size of a cell phone data plan and the number of text messages sent is your answer

2 1/6 × 4 1/2
Answer: 1 1/2, 3/2, or 1.5
Step-by-step explanation: Convert expression into unproper fractions, 13/6, and 9/2. Then by changing 13/6 into a denominator with 2, you multiply and it equals 1 1/2.
1/2 = 1/a + b/c make b the subject
Answer:
b = [tex]\frac{ac-2c}{2a}[/tex]
Step-by-step explanation:
Given
[tex]\frac{1}{2}[/tex] = [tex]\frac{1}{a}[/tex] + [tex]\frac{b}{c}[/tex]
Multiply through by 2ac to clear the fractions
ac = 2c + 2ab ( subtract 2c from both sides )
ac- 2c = 2ab ( divide both sides by 2a )
[tex]\frac{ac-2c}{2a}[/tex] = b
A jeweler has several boxes of earrings to ship to a store. Each box is a cube with a side length of 5 centimeters. The jeweler packs the boxes in a shipping container. The filled container has 4 layers, where each layer contains 7 rows and 10 columns of boxes. What is the volume of the shipping container?
Answer: [tex]35,000\ cm^3[/tex]
Step-by-step explanation:
Given
The earring box has a volume of [tex]a=5\ cm[/tex]
It is packed and loaded in the container which has 4 layers and each layer has 7 rows and 10 columns
We can say that each layer can hold [tex]7\times 10=70\ \text{boxes}[/tex]
The volume of each earring box is
[tex]V_o=a^3=5^3\\V_o=125\ cm^3[/tex]
Four layers can hold [tex]4\times 70=280\ \text{boxes}[/tex]
the container can hold 280 boxes
[tex]\therefore \text{Volume of container is}\ V=280V_o\\\Rightarrow V=280\times 125=35000\ cm^3[/tex]

3n^3 - 12n^2 + 2n - 8
(show the work pls..)
Answer:
The answer will be ( n - 4 ) ( 3n² + 2 ).
Step-by-step explanation:
1) Factor out common terms in the first two terms, then in the last two terms.
[tex] {3n}^{2} (n - 4) + 2(n - 4)[/tex]
2) Factor out the common term n - 4.
[tex](n - 4)( {3n}^{2} + 2)[/tex]
Therefor, the answer is ( n - 4 ) ( 3n² + 2 ).

Answer:
Angle 1,Angle 4
Step-by-step explanation:
They're
The value of angle ∠1 and angle ∠4 will be congruent with angle ∠8. The correct options are D.
What are lines and angles?Lines are straight with little depth or width. Perpendicular lines, intersecting lines, transversal lines, and other types of lines will be covered. An angle is a shape formed by two rays emerging from a common point. In this field, you may also come across alternate and corresponding angles.
Given that there are two lines e and f cut by the transversal line g making different angles.
From the property of the alternate interior angles the two angles, 1 and 4 are congruent to angle 8. The value is mathematically written as,
∠1 = ∠4 = ∠8
Therefore, the value of angle ∠1 and angle ∠4 will be congruent with angle ∠8. The correct options are D.

Find the value of each variable.
Answer:
5. x= 13 y= 18.4
6.
Step-by-step explanation:
question 5:
tan45=x/13
multiply both sides by 13 to get x by its self.
end up with 13×tan45 so put that in the calculator to get x
then you do cos45= 13/y
multiply by y on both sides.
end up with y×cos45=13
divide the cos45 by both sides
put 13/cos45 to get y
question 6:
sin30=4/x
multiply x on both sides
end with x×sin30 =4
divide sin30 on both sides
put 4/sin30 in a calculator to get x
same thing again but with tan30 ahaha
